HAY RAKE AND LOADER.

To all whom 2'25 may concern.

Be it known that I, CHRISTIAN CHRIS- TIANsnN, a citizen of the UnitedStates, residing at Kenmare in the county of Ward and State of NorthDakota, have invented certain new and useful Improvements in Hay Rakesand Loaders; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in hay rakes and loaders.

One object of the invention is to provide a machine of this characteradapted to be connected to and drawn along by the wagon into which thehay is to be loaded and hav ing means whereby the elevating mechanism ofthe loader is connected to and driven by one of the wheels of the wagon.

Another object is to provide a machine of this character which will besimple, strong and durable in construction, efficient and reliable inoperation and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure 1 is a plan view of my improved hayrake and loader showing the same operatively connected to a wagon; Fig.2 is a rear view of the same; Fig. 3 is a front or outer end view of themachine; Fig. 4 is an inner or rear end view thereof; Fig. 5 is avertical longitudinal sectional View; Fig. 6 is a detail perspectiveview of the wheel clamp.

In the embodiment of the invention I provide a main supporting framecomprising a platform 1 to the upper side of which are secured forwardlyprojecting converging angle iron draft bars 2 in the outer ends of whichis secured the upper end of a caster wheel standard 3 on the lower endof which is arranged a caster wheel 4. To the stand=- ard 3 is connecteda draft hook or clevis 5. On the opposite ends of the platform 1 aresecured bearing brackets 6 and 7 in which are revolubly mounted sprocketgears 8 and 9 with which is engaged and driven the elevating mechanismhereinafter described. The brackets 6 and 7 are provided with rearwardlyprojecting extensions 10 having Specification of Letters Patent.Patented June 18, 1912- Application filed April 10, 1911.

on their outer ends vertical bearings 11 with which are pivotallyconnected the upper ends of runner standards 12 on the lower ends ofwhich are formed flat rearwardly projecting feet or runners 13 wherebythe rear portion of the machine is suitably sup-.

ported when drawn over the ground.

To the rear edge of the platform 1 is secured a series of rake teeth ll'said teeth being preferably formed in pairs from a single spring metalrod bent into substantially U shape. The rods after being bent inU-shape are each preferably bent to form a spring coil 15 and the lowerportions of the teeth formed by the ends of the rod are preferably bentor curved forwardly to a slight extent as shown. The upper looped endsof the teeth are secured to the rear edge of the platform preferably bya series of clamping plates 16 which are riveted through the looped endsof the teeth to angle iron metal binding strips 17 secured to the rearedge of the platform as shown.

The outer end of the binding strip 17 is extended and bent forwardly atthe outer end of the machine as clearly shown in Fig. l of the drawingand to said extending end of the strip are secured additional rake teeth18 the purpose of which will be hereinafter described. The rake teeth 18are constructed and secured to the angle iron strip 17 in the samemanner as the teeth 14. Arranged in rear of the teeth 14 and looselysupported by means of links 19 which are engaged with the coils 15 ofthe teeth is a drag bar 20 which is provided to assist the teeth 14 incleanly raking up the hay. On the front edge of the platform is securedan angle iron binding strip 21 the outer end of which projects beyondthe outer end of the machine and is bent forwardly to form a 'brace withwhich the forward end of the extension of the strip 17 is connected.

Arranged above and supported in an inclined position on the platform 1is a hay elevating frame or chute 22 comprising a base or bottom member23 to which are secured inclined side bars 24:, said bars being securedto the base by suitable supporting brackets as shown. The lower outerend of the base or bottom plate 23 is secured and supported by thebrackets 7 at the outer end of the platform 1 and its inner higher endby a supporting brace 25. The opposite ends of the base 23 are notchedand to the lower end of the base are secured the upper a sprocket gear29. Passing around the sprocket gears 8 and 9 of the frame and the gears27 and 29 on the chute is a sprocket chain 30 whose links at certainintervals carry elevating teeth 31 which when the chain is driven in theproper direction will engage the hay as it is raked up by the rake teethand will convey the hay up the chute 22 and discharge the same over theupper end of the chute into the wagon body B to which the machine isattached. The teeth 31 are here shown in the form of wire rods havingtheir inner ends bent at right angles to form attaching members andhavin their outer ends curved slightly and inserted through apertures inclamping plates 32 which are riveted to lateral extensions 320 formed onthe opposite sides of certain of the chain links as shown. By providingthe sprocket 29 and arranging the same in the bracket or hanger 28 asherein shown and described the chain at the inner end of the machinewill be held back to a position where the same will notinterfere withthe arrangement of'the upper end of the chute thus permitting said endto project over the top of the wagon body B and to properly dischargethe hay therein.

On the upper end of the chute are ar ranged spring guards or guide bars33 over which the hay is drawn by the elevating chain and the haydirected from the end of .the chute onto the wagon. On the lower end ofthe chute and connected tothe side bars 24 are guide bars 34. Secured tothe extended outer end of the strip 17 to which the rack teeth 18 areattached are upwardly extending guide bars 35 which together with theguide bars 34 hold the hay in engagement with the elevating teeth on thechain while being brought around the forward lower end of the elevatoror chute.

The machine is connected to the wagon at its forward end by a suitabledraft rod 36 which is connected to the clevis 5' on the standard of thecaster wheel 4, said draft rod having its opposite end connected to thewagon B in any suitable manner. The machine is also connected to theadjacent rear wheel W of the wagon by a combined attaching and operatingshaft 37 which is preferably formed in two or more sections, saidsections being connected together by universal joints 38, whereby saidshaft is made flexible. The outer section of the shaft 37 is revolubly'mounted near its inner end in a bearing bracket 39 and at its outer endin the bracket 7 of the outer sprocket wheel 9. Pivotally connected tothe inner end of the inner-section of the shaft is a wheel clamp '40comprising a body bar 41' on which mid-way between its ends are formedpivot lugs 42 through which and through the end of the shaft is passed apivot pin or bolt 43. The opposite ends of the bar 41 are adapted toengage the'outer sides of two spokes while with the. oppositesides ofthe spokes are engaged 'clip plates 44 through which and through theends of the bar 41 are inserted bolts 45 whichwhen screwed up will drawthe plates 44 and ends of the bar 41 intorigid engagement with twospokes on opposite sides of the hub as shown. The ends of the plates 44are preferably bent inwardly to a slight extent to form right angularfeet 46 which engage the sides of the spokes and prevent the plates andthe clamped ends of the bar 41' from slipping laterally on the spokes.By thus connecting the inner end of the shaft 37 to thewheel the shaftwill be driven by the movement of the wheel. The movement of the shaftwhen thus driven is imparted to the elevating chain by a bevel gear 47which is in operative engagement with a bevel pinion48 fixedly mountedon the adjacent end of the shaft of the sprocket gear 9 whereby thelatter is driven and the sprocket chain thus operated in the properdirection for elevating the hay in the manner described.

lVith the above construction of this machine, the operation is asfollows: As the wagon B progresses along the field, the draft rod 36draws the plat-form and rakes along a line parallel with the course ofthe wagon, which will be toward the top of the sheet bearing Fig. 1.Meanwhile the wheel W through the wheel clamp shown in Fig. 6 rotatesthe shaft 37 which through the bevel gears 47 and 48 drives theelevator. The rake teeth 14 and 18 gather the hay from the surface asthe rakes move over it, and the elevatorteeth or fingers 31 (followingthe course shown by the arrows in Fig. 2) carry the hay along outwardbeneath the platform and around under its outer end over the guide bars24 and under the guide bars 34 and .35, and thence carry it upward overthe elevator and deliver it and fall and to move irregularly as it willof necessity do while traveling over the field, and the shaft and thewheel clamp 'serve the further function of holding the platform out fromthe wagon while it is drawn forward by the draft rod 36. The drag bar20, hung on links 19 from the coils 15 of the teeth 14, I find to beextremely useful in normally preventing hay from passing between theteeth while yet permitting the passage of a stone or other obstruction.The outer teeth 18 I find useful for preventing the fingers 81 frommoving the hay collected by them off the outer end of the series ofteeth 14, rather than carrying it up over onto the elevator as isdesired.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood with out requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invent-ion as defined in theappended claims.
